ATMATICALLY-OPERATED OIL BURNER.

Applicationk med' April 4,

improvedoil burner, and Fig. 2 kis a top Y plan thereof.

Our invention is not restricted to the pre oise construction andarrangement of parts herein shown and described, nor to the va# riousdetails thereof, as the same may be modified or rearranged in variousparticulars without departing from the spirit and scope of ourinvention, one practical 4embodiment of which has beenherein'illustrated and described withoutattempting to show all of thevarious forms and modiiications in which our invention might beembodied.

Our device comprises an upwardly coned hollow inclosure 1 having severaloutwardly directed horizontalbottom lugs 2 secured by bolts 3 and nuts 5to registering end lugs 4 of a basal member 6 which has openings 7. Theupper end of vthe inclosure `1 is open. The basal member 6 is shapedwith a circular central portion 8 with raised rim as an oil drip cuparound and integral withA an axial and fixed hollow cylindrical oildelivery conduit 10-11 whose upper portion above the cup 8 traverses thehollow'of l,

the inclosure 1 centrally to project terminally thereabove and has aspreader dis` coidal or annular plate 17 lixed upon its upper end over aconstricting annulus 16 fixed in the upper part of thevbore of theconduit, which thus limits the delivery of oil upwardly over and uponsaid plate 17. The lower end of the conduit 10 which depends below saidinclosure 1 is closed by a plug 13 sealed therein which has an upwardlyopening conical step bearing hollow 14 to step therein antifrictionallythe conical lower end of a rotary axial shaft 18 een trally in thehollow 12 of the conduit and to project above said spreader plate 17 Vtocarry fixedly a somewhat wider circularv plate Von its upper end atl 21.

The numeral 24 denotes a disk positioned below the spreader plate 17 andjust above 192e.V serial 1101.262280.

the openv top.l of the inclosure 1 and whose marginal part is cut andshaped with ay number of circumferentially.y arranged inclined vanes:26. The inner' raised rimof the disk Vat V25 surrounds the upper vanddiminished termination of the conduitipart 11 in spacedfrelation andhorizontally. Bolts V22 and nuts 23 secure iixedly vthe disk 24,'to

and depending from the top fplate 21 outside of and below the spreaderplate 17 .y

The lower conduit part 10 has a threadedy aperture to seat a threadedend of an oil supply pipe 15 which should leadto'a tank of fuel oilunder head. The drip cup 8 has 1n itsbottoni a threaded hole in which issecured the threadedvend of a conduit 9 to drain oil from the cup to asuitable receptacle not shown.

The inclosure 1 may be mounted iny thev When it is desired to operatethe burner, ik

oil is supplied the conduit 10-11 under head which oil issues at the topflowing equally outwardly radially over the circular spreader plate 17and droppingin drops upon the disk 24 inside the vanes 26 but which,when the disk and vanesare rapidly rotating is thrown out-upon and fromthe vanes horizontally around the upper edge of the inclosure 1, beingatomizedthere in v a misty condition and mingled with air constantlydrawn by suction throughlthe coni; cal inclosurev 1 anc then through theinterstices of the vanes. The disk 24 andyits vanes 26 are initiallythrown into rotation manually while a piece of blazing paper or othermaterial is held-near the vanos which pick up and atomize and deliverthe o1l into the Zone 1n which the igniting material is positioned,igniting the oil, and which causes a wide annular zone of Vflame-around,

the vanes which are 4kept automatically in inclosure 1.r This air draftkeeps the conduit 10-11 cool, necessary in'this class of oil burners.Any overflow of oil from'the disk 24 passesinto the cup `8 and drainsaway by the pipe 9. Oil delivery and relaas specified by valve pipe 15.

. tive speed of the vanes are valve controlled,

Having described our invention, what wc claim' as new, and desire tosecure by Letters Patent, is z An oil burner, comprising in combination,an openend inclosure, a conduit in ,communication with a supply of fueloil under head and traversing said inclosure centrally to have its upperdelivery .end project thereabove the lower end of the conduit beinclosedby a step-bearing, said conduit having a concentric encircling oildrip-cup Within the lower part of said inclosure, said drip cup havingdrainage means, an annular spreader plate mounted concentrically aroundthe upper end of the conduit toreceive oil therefrom, a shaft mountedaxially Within said conduit and stepped in said step-bearing andprojecting above the con duit and inclosure, said shaft being spacedfrom the inner wall of the conduit, a disk secured coaxially upon theupper termination of said shaft, anA annular plate positioned below thespreader plate coaxially and rotatably and above the top of saidinclosure, saidy annular plate having peripheral vanee, and connectingmeans between said disk and said annular plate, said tures.
